The concept of a national park differs from nation to nation. In Australia, the United States and Japan the land in national parks is government-owned and the management of these parks is decided by government policy. Activities such as housing or industry within the parks are discouraged. In Britain, national parks are quite different. Parks such as the Lake District, Dart Moor and Exmore include towns and villages where large numbers of people live. Much of the land in these national parks is privately owned, but there are strict controls on its use, and on the appearance of the landscape and buildings, some of which (including whole villages) are heritage items. This style of national park is well suited to the scenic areas of Britain where human influences such as houses, farms and fields are part of the beauty, and combine with natural scenery to produce an overall attractiveness. In Africa and Southern Asia, large national parks have been set up to preserve animals in particular. The land within these national parks is owned by the government, but there are many private developments, such as hotels and shops, for the visitors who come to see the animals.
